Just made an appointment with Modern Musclecar in Fraser, Michigan for two pulls next wednesday. Gonna' make one stock and one with the PSP. I'm not sure if I'm going with the K&N on the stock pull or not. I'd really like to see what the PSP alone will do. Two pulls for $75.00

 

Found this shop in San Diego that does 3 runs for $50. Best I could find in SD.

Red2000SVT,

Lets see your dyno numbers with the dyno set in the SAE mode, instead of STD mode.

With the dyno set in the STD mode it is reading un-corrected horsepower.

With the dyno set in the SAE mode it is reading corrected horsepower, which is truer.

Just a little note to let you know!

I thought all Dynojet's measured corrected #'s?

I know there is a couple of other types of dyno's out there.

I'm going back to that shop and have my stang dyno'd. I'll ask about the SAE/STD and get SAE print out if its uncorrected right now and repost.

Red2000SVT,

Was just letting you know, no problem!

You might be surprised when you see the corrected numbers with the dyno set in the SAE mode.

Your horsepower will be lower!

First of all, corrected #s in the summer months in most parts of the U.S. will be _higher_ due to all the crappy air we get. Last time I dyno'd my 'Stang was in May of this year. 80.6^F, 29.48" baro. press., 0.49hg vapor pressure. This yielded a 1.04 correction factor. Test in the middle of winter, and you'll see negative correction factors (like 0.95 or more).

Oh, and FWIW, on my graphs it shows "STD Horsepower" and "STD Torque", and they were the corrected figures.

WA 2 FST,

Well all I can explain is my Dyno run that were done here in South Florida on July 1, 2000.

With the Dyno set on STD Horsepower my truck made 375.1 HP & 441.5 Torque.

With the Dyno set on SAE Horsepower my truck made 368.1 HP & 436.5 Torque.

Both of these dyno runs were with my 2000 Lightning with Pro-M 80mm Mass Air, Swanson Performance Computer Chip, and 40 Series Flowmaster Mufflers.

SAE is the proper setting to read corrected horsepower……………

RED2000SVT - Where is the Shop in SD. For 50 bucks I'll get base readings before my Truck Mods.

Thanks

Got them done at PowerHouse Motorsports in Escondido. They are just off of Grand past Ash street behind the AM-PM on the left. Ash is HW78 that comes into Escondido from the east.

FSUFAN - Did you run on a DynoJet for a different type of dyno? They said these #'s are corrected with a 1.04 correction factor for that day (temp, pressure ect....) and they run the WinPEP software (lastest and greatest version).

Ran my 98Stang and got 277rwhp5700 and 315rwtq@3500. It has a MAF problem in that it is maxed out for 19# injectors and the blower has 30# injectors. The computer is supposed to be able to handle the cross calulation to make up for it but my A/F ratio is between 11-12:1. Kinda rich. Got the A/F ratios at a different shop last week.

Red2000SVT,

All my dyno pulls were done on a Dynojet with Win PEP software also.

I have seen other's go to speed and performance shops where they dyno vehicles. The shop does the pulls with the dyno set on the STD position knowingly the dyno will show a higher reading.

I’m by no means saying that this was done in your case.

I have seen folks come into the performance shop where I have done all my dyno runs, and put their vehicle on the dyno and it shows less horsepower & torque then there previous dyno pulls from another shop. Then you look at their dyno pull charts and you see they were done with the dyno in the STD mode.

Just a little note for peace of mind, next time just for kicks have them put the dyno in the SAE, the corrected horsepower setting and see if there is a difference.

Good Luck!

Hey guys, Sal here. I just want to back up what FSU has said. STD is actual numbers, and SAE, is corrected numbers. Actual numbers are hardly ever used, and fankly, for tuning purposes, they are pretty useless. SAE corrected numbers are what is favored. SAE correction, will "adjust" the numbers based on an SAE standard value. This value is the same in all Dynojets. So if a guy in CA dynos his truck and the weather is BP 29.30, temp 90*, hum- 85%, and a guy in NY dynos his truck and the weather is BP 30.90, temp* 50, hum- 30%, and both dynos are printed in SAE corrected numbers, then you can honestly "compare" the two readings fairly. Also, if you are doing testing on the dyno, and making changes, you want SAE corrected numbers because you eliminate the weather as a variable, and get correct gain/loss numbers. Now let's say you want to see what new blower pulley does. At 10 am, it's sunny, warm and dry. You make an actual pull for a base number. Then you take an hour to do the pulley swap, and now it's a bit overcast as a storm is approaching, and it's humid out. You make another pull with the pulley, and WHAT?! less power. But if you had done it with corrected numbers, you would have seen a gain See how it works? Hope this clarifies the dyno thing a bit.

Sal,

Thanxs for explaining the dyno senerio better way.

Could you please call me at (786) 236-5486 so I can discuss some chip tuning questions with you.

Thanks,

Matt

I agree with everything both of you guys are saying about "corrected" numbers...that's why they use a "correction factor" to the SAE standard. This has been done every single time I've ever been on the dyno with any of my vehicles.

As FSU has pointed out, many times they'll even let you see both graphs side by side...which is pretty cool. Certainly if you dyno'd in good air, the STD figure will be higher than the corrected SAE figure.

Down here in N. TX if you do pulls at any time from April to Sept., you're going to have a _positive_ correction factor. That's why my 597rwhp LX only runs 134mph through the traps. My _actual_ HP when I'm racing is typically lower than what the engine actually produces at the rear wheels---if we're using corrected figures.

I think the key, no matter what, is to make sure the dyno operator is using whatever wet bulb device, etc. to get the correction factor right.
